The 108MP sensor of the Galaxy S21 Ultra 5G

The main rear camera of the Samsung Galaxy S21 Ultra 5G captures images at 108 megapixels, the central sensor of your phone for everyday photos. This optical module groups together the lens, CMOS sensor and image processing circuits, all integrated into a single block that attaches to the back of the device. When photos display blurred, dark or no longer take at all, it is often this component that fails, and replacing it restores the original photo quality.

This part is original Samsung manufacturer equipment, extracted from production devices and subjected to a battery of tests before shipment: signal, sensors, optics, data display. Each module is cleaned and certified compliant with original assembly standards, which guarantees total compatibility and performance without compromise during integration.

Why choose an original camera rather than a copy

Poor quality optical modules degrade photos immediately: overexposure, loss of detail, color processing out of adjustment. An original camera reproduces exactly the Samsung rendering, optical and electronic block identical. Cheap copies use lower-power sensors and uncoated lenses, and no software compensates for this gap once the device is repaired.

A tested original part in the workshop offers the certainty that the module works at 100% before being shipped: active sensor, smooth autofocus, correct EXIF reader. This is the control that distinguishes a reliable part from a part declared functional without real verification.

Package contents and installation

You receive the main rear camera module alone, ready to be integrated into the Galaxy S21 Ultra 5G. Installation requires unsticking the optical block from its housing, connecting the connector ribbon to the motherboard, then securing it again with the provided adhesive. This operation is performed in a few minutes with minimal tools (precision screwdriver, fine tweezers). If you are in a workshop, this replacement proceeds without difficulty, if you do it yourself, take care not to damage the ribbons when disconnecting.

Compatibility and verification before ordering

This camera is intended exclusively for the Samsung Galaxy S21 Ultra 5G. Before ordering, check the model written under the battery of your phone (G998B) or in the system settings (Settings > About phone). Nearby models such as the Galaxy S21 or S21 Plus use different modules, as do the 4G variants of the S21 Ultra. A serial or model number misread at the time of ordering results in the shipment of an incompatible part.

Warranty and assistance

This part benefits from a 2-year warranty from the date of receipt. It covers any malfunction of the module (inactive sensor, blocked autofocus, missing EXIF data). The warranty does not cover installation damage, impacts received after delivery, or normal wear of the module after normal use in a workshop or on a personal device. If a problem occurs within the specified period, the part is replaced free of charge.
